A US haunted house is so scary the owner makes visitors sign a 40-page waiver and provide a doctor's note - but if you are brave enough to get through it without screaming out your safe word, you'll be awarded $20,000 (£15,560).
McKamey Manor is so horrific no one has ever completed it, despite the impressive prize on offer.
Russ McKamey, who owns the creepy attraction, has launched a new show Desolation, which he says is he most 'extreme' so far and judging by the photos, I think he's probably spot on.
Speaking to WGNTV, Russ said: "Nobody's even made it to the starting clock with this new show.
"With the new mental game, it's much more difficult. And because of that, no one's even started the clock."
The entrance fee is a bag of dog food for one of Russ's five pooches, however, if you fancy the challenge there's a whole host of conditions you'll need to meet.
First off, you'll need to be at least 21 - if you're 18 to 20, you'll need parental permission. You'll need to undergo a 'sport physical' and provide a doctor's note stating you are physically and mentally well.
You'll have to pass a background check carried out by the team and will be screened over FaceTime or a phone call; you'll also need to bring proof of your medical insurance and sign a whopping 40-page waiver.
Oh, and there's a drugs test on the day to check you're not under the influence.
All participants must watch a video entitled And Then There Were None, which is a two-hour long compilation of people who have failed to get through the experience while a voice repeatedly says: "You really don't want to do this." Sounds fun, eh?
Russ says he's spent more than a million dollars getting it up and running and, fair play, it does looks very impressive.
Russ says he gets his inspiration from horror movies, adding: "I'm a very straight-laced conservative guy, but here I run this crazy haunted house that people think is this torture factory, fetish factory.
"All of these things that it's not, but people believe that based upon the films that I have made."
